The scales cover the whole body except the top of the head, a 

 single row of smaller scales protects the base of the soft dorsal and 

 anal tins. The colour of the larger specimens is uniform dull 

 silvery gray, but young specimens show a black blotch above the 

 anal spines, and something resembling a black vitta on the posterior 

 portion of the lateral line ; there seems also to have been a black 

 opercular patch. 



A number of specimens were brought from Goldie River and 

 other fresh water streams, varying in size from 7 to 2 inches in 

 length.
